I’ve done a system update recently via pamac, rebooted. Now I get following errors every time I power off the machine:
sd-umoun: Failed to unmount /oldroot: Device or resource busy sd-umoun: Failed to unmount 20: No such file or directory ACPI BIOS Error (bug): Could not resolve [\_PR.CPU0._PPC], AE_NOT_FOUND (20180810/psargs-330) ACPI Error: Method parse/execution failed \_PTS, AE_NOT_FOUND (20180810/psparse-514)
The first couple most likely was caused by systemd update, but I’m really confused about the ACPI related ones.
Please help to diagnose them
Just for the record
CPU: Intel Celeron N4000
